Sakkari won the game and then served out the match to win 3-6 6-3 7-5.

Pliskova did not shake Mrozinska's hand and instead smashed her racket several times against the side of the umpire's chair, breaking the wood.

Pliskova's twin sister Kristyna, who is also a professional player, subsequently tweeted "the worst i have ever seen wta and i hope this lady Marta Mrozinska will never ever judge any match of me or Karolina again .blacklistforever"
